Box 9277 Corpus Christi, Texas 78469-9277 RE: AMENDMENT NO. 2 TO PROFESSIONAL SERVICES CONTRACT Elevated Water Storage Tanks Citywide (ACR Implementation) City Project E16290 Mr. Edmonds: In response to the City's request, we are proposing Amendment No. 2 in the amount of $39,515 to provide additional services for the Elevated Water Storage Tanks - Citywide (ACR Implementation) project (E16290) for a total re-stated project fee of$730,049. PROJECT BACKGROUND Original Contract On October 13, 2016, LNV received formal Notice to Proceed (NTP) for project E1690 — Elevated Water Storage Tanks Citywide (Alternative Capacity Requirement Implementatlen.) The project consists of providing the City with a 2.5 million gallon (MG) elevated storage tank (EST) at Starry Road and a 1.25 MG EST at Nueces Bay Blvd., as outlined in the Alternative Capacity Requirement (ACR) Implementation Plan. This project also includes the demolition of the four (4) existing ESTs in the City's Pressure Zone 1, which are identified as Morgan EST, Gollihar EST, Alameda EST, and Flour Bluff EST. The original contract amount for the Basic and Additional Services associated with this project is $672,034. Amendment No. 1 On April 18, 2017, LNV received formal Notice to Proceed (NTP) for Amendment No.1 to provide the City with modeling assistance in which the Flour Bluff area receives water from the mainland. The water modeling support provided for this task consisted of evaluating if adequate redundancy exists with respect to water delivery to the Flour Bluff area, improvements that would improve water quality in the Flour Bluff area, and the appropriate location for Starry EST with respect to pressures/water quality. This modeling support assisted the City in implementing waterline improvements needed along Yorktown Blvd. and Flour Bluff Drive, in addition to, the relocation of Page 1 of 5 801 NAVIGATION I SUITE 300 I CORPUS CHRISTI,TEXAS 78408 OFFICE 361.883.1984 I FAX 361.883.1986 I WWW.LNVINC.COM EXHIBIT A Page 1 of 5 the new 2.5 MG EST from Starry Road to Division Road to improve pressures and overall water quality in the Flour Bluff area. PURPOSE OF AMENDMENT NO. 2 The purpose of Amendment No. 2 is to include the demolition of the 12.5MG Holly Ground Storage Tank (GST) and the installation of generators at the two (2) new ESTs into the scope of work of this project. Due to the demolition of the City's four(4) existing ESTs being included in the scope of this project which will require a contractor who specializes in demolition, it is recommended for the City to include the demolition of the Holly 12.5MG GST in this scope of work since it has been decommissioned and is no longer in use in the City's water distribution system. In addition, it is also recommended to add generators into the scope of work of this project at both new EST locations to provide backup power at each EST if a power interruption ever occurs. The backup power will provide the City the ability to control the ESTs during a power outage, which is vital source to operations for alleviating surge and sustaining adequate pressures in the system. The scope of work specified herein is based on the following assumptions: • Demolition of the Holly 12.5MG GST will include only the removal of the GST and utilities to a depth of 3 feet below grade at the location of the GST. All utilities routed to the GST will be abandoned in place and capped off at the limits of the demolition. • Holly 12.5MG GST lead and asbestos contamination will be confirmed to exist and/or not exist during the design phase either by original construction records review or by material testing. • The City will provide all required coordination with TCEQ required for decommissioning of the Holly GST; however, an additional proposal can be provided if it is preferred for the Engineer to provide TCEQ coordination. • Generators to be included will have the capacity to supply power for running electrical loadings being designed for at the two (2) EST sites to include lighting, security system, instrumentation, IT equipment, and Police communication equipment. • Generators will be diesel engine driven with auto transfer on power failure. • Diesel fuel storage capacity on site will be for 48-hours full operation run time. • Generators will be mounted to a concrete slab and provided with a weather proof enclosure that will provide adequate exhaust ventilation. • Generators will be designed to be located outside of each EST on a concrete slab on grade separate from the EST foundation. SCOPE OF WORK BASIC SERVICES Preliminary Phase • Request and review available reports, record drawings, utility maps and other information provided by the City pertaining to the Holly GST project area.

Design Phase • Provide demolition plan/detail sheets (two (2) plan sheets anticipated)for the 12.5MG Holly GST demolition that will be incorporated into the 60%, 90%, and final plan set submittal. • Provide concrete slab on grade details (two (2) plan sheets anticipated)for the generator to be installed at each site that will be incorporated into the 60%, 90%, and final plan set submittal. • Provide electrical details (two (2) plan sheets anticipated)for the all electrical, controls, and instrumentation required for the connection of the generators at each site. These details will be incorporated into the 60%, 90%, and final plan set submittal. • Prepare and incorporate the technical specifications required for the 12.5MG Holly GST demolition and generators being added at each EST site. Construction Administration Phase • Additional time anticipated during the construction phase to provide engineering services for completing the following tasks: ➢ Review Contractor submittals and coordinate Contractor submittal review with subconsultants related to the 12.5MG Holly demolition and installation of generators at each EST site. > Review Contractor provided construction "red-line" drawings and prepare project record drawings for the 12.5MG Holly demolition and installation of generators at each EST site. ADDITIONAL SERVICES Environmental Issues • Perform an asbestos and lead survey of the 12.5MG Holly GST to include sample collection and analysis for determining if asbestos or lead exists and mitigation required for removing any hazardous materials found.
